TOOL FOR TRUING WELL-ROD JOINTS.

SPECIFICATION forming' part of Letters Patent No. 584,439, dated J' une15, 189'?.

Application filed April 10, 1896.

T all wiz/0m it nwty concern.'

Be it known that I, JOSEPH H. VIEHL, a citizen of the United States,residing at Ilarmony, in the county of Butler and State ofPennsylvania,have invented a new and useful Tool for Truing Vell-RodJoints, of' which the following is a specification.

The purpose of this invention is to devise means for truing the jointsof well drilling and boring machinery in the field and at the place ofoperation and thereby obviate the expense, loss of time, and annoyanceoccasioned by having to transport the parts to be repaired or trued to amachine-shop.

By this invention joints that have been loosened can be tightened,thereby enabling theV operation of drilling and boring to proceedWithout necessitating the carrying of various sets of tools, so that oneset can be used while another is sent to the shop for repairs, orwithout requiring the shutting down of operations during the interim ofsending the tools to a distant shop.

This invention has for its object, further, to provide an apparatus ormachine simple in construction and easy of manipulation and which willeffect the desired end in a thorough manner.

For a full understanding of the merits and advantages of the inventionreference is to be had to the accompanying drawings and the followingdescription.

The improvement is susceptible of various changes in the form,proportion, and the minor details of construction without departing fromthe principle or sacrificing any of the advantages thereof, and to afull disclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which Figure lis an elevation of a machine orapparatus for carrying out the objects of this invention. Fig. 2 is atop plan View thereof. Fig. 3 is a detail view of the yokes or clamps bymeans of which the machine is secured to the drill or tool. Fig. 4. is aside view show ing the means for connecting the endsof the yokes orclamps and securing the adjacent end of the arch between them. Figs. 5and 6 are detailviews of the tool-holder. Fig. 7 is a detail view of theadjacent ends of the drill or tool and the toolcarrying staif.

Serial No. 587,053. (No model.)

Corresponding and like parts are designated in all the figures of theaccompanying drawings and referred to in the following description bythe same referencecharacters- The numeral l represents a drill, bit, orboring-tool of ordinary construction, such as generally employed fordrilling Artesian and oil wells, and is formed at its upper end with apin or shank 2 of frusto-conical shape `and which is adapted to enter asocket 3 of corresponding outline provided in the end of thetool-carrying staff 4. These parts are illustrated simply to show theapplication of the invention.

The machine or apparatus comprises yokes or clamps 5 and 6 of similarconstruction and having transverselyapertured heads 7 at their ends,which aline whenthe parts are properly assembled and receive bolts 8, by

means of which the yokes or clamps are connected together and securedupon the drill or boring-tool l, as indicated in Figs. l and 2. V-shapeddepressions 9 are formed in the inner faces of the yokes or clampsmidway of their ends, so as to receive the drill or boringtool l betweenthem and enable the said yokes or clamps to secure an extended purchaseagainst the sides of the said drill. Each yoke or clamp has a socket atits outer side to receive a handle l0, which is grasped when rotatingthe apparatus upon the drill to dress or true the pin or shank 2.

A holder for the truing or cutting tool ll is provided and applied toone of the yokes, as 6, and comprises a plate 12, fitted against aflattened portion 13, formed on the said yoke 6 and secured thereto byclamp-bolts 14., and each of the parts l2 and 13 having a semicirculargroove or channel, which when the said parts l2 and 13 are placedtogether provide a circular opening or passage for the reception of asleeve l5, in which is fitted the truingftool ll.

The truing-tool l1 is angular in cross-section and is of besttool-steel, highly tempered, and is adapted to be adj ustably fitted inan opening 16 in the sleeve l5 of corresponding shape to thecross-sectional area of the said tool 1l. The sleeve l5 is composed oflongitudinal sections, preferably halves, which are adapted to becompressed so as to grip the tool 1l and hold the latter in the locatedposition, the bolts 14 being employed for this purpose. By having thesleeve 15 circular in form it can be turned to any angle in thetool-holder so as to present the cutting edge of the tool 11 to the workat any desired inclination, according to the nature of' the cutrequired. In addition to its rotary adjustment the sleeve 15 is capableof' longitudinal movement within the tool-holder, and the same meansemployed for securing the sleeve likewisecompress the same upon the tooll1, so as to hold itin therequired position within the said sleeve. Vhenit is required to adjust either the tool 11 or the sleeve 15, orboth,the bolts 14 are loosened, and after the required adjustment is attainedthe said bolts are retightened and thereby fix the relative position ofthese parts.

An arch or stirrup 17 is provided at its ends with sleeves 18, which aretransversely apertured and come between the heads 7 of the yokes 5 and6, the openings in the sleeves 18 registering with the apertures oropenings in the said heads 7, so as to receive the bolts 8, by means ofwhich the parts are connected together. Adjusting-nuts 19 are mountedupon the threaded ends of the bolts 8 and serve to hold the yokes 5 andG in the adjusted position. Butters 20, of rubber, or metallic springsare interposed between the adjusting-nuts 19 and the adjacent heads ofthe yoke G and are designed to provide for a slight movement andrelative separation of the yokes when meeting with any unevenness orprojection of the drill or boring tool, thereby obviating a straining ofthe apparatus. A set-screw 21 is centrally located with respect to thestirrup or arch and operates in a threaded opening formed therein, andits inner end is pointed, so as to enter a central depression in the endof the pin or shank 2, whereby the machine is centered and steadied whenin operation. Bya proper adjustment of the set-screw 21 the apparatus ormachine can be raised or lowered so as to dress, true, or turn down theshoulder 22, formed at the base of the pin or shank 2, when required totake up any looseness in the joint or to true the same.

Suppose it be required to dress the shoulder 22 of the drill orboring-tool. The apparatus or machine is fitted upon the said drill byreceiving the latter between the yokes 5 and 6 and the set-screw 21 isadjusted so that the said shoulder may be dressed to the required depth,and the trning-tool 11 is adjusted to the required angle and so that itsinner end will touch. the base of the pin or shank 2, after which thehandles 10 are grasped and the apparatus rotated until the shoulder 22is turned down or dressed the required distance to secure a true andtight joint.

Having thus described the invention, what is claimed as new is- 1. In amachine for truing joints, the combination of similarly-formed yokes orclamps inversely disposed and having apertured heads at their terminals,a trning-tool having adjustable connection with one of the yokes, anarch having its extremities apertnred and fitted between the heads ofthe yokes, fastenings passing through the alining openings of the saidheads and apertured extremities of the arch, and adjusting means appliedcentrally of the arch to limit the advance of the cutter, substantiallyas set forth.

2. ln a machine for truing joints, the combination ofoppositely-disposed yokes having their end portions formed withtransverselyalining openings, a truing-tool provided on one ot' theyokes, an 'arch having its end portions coming between the terminals ofthe yokes and formed with transverse openings to correspond with theopenings in the yoketerminals, a set-screw at the central point of thearch, and bolts passing through the alining and registering openings ofthe yokes and arch, substantially as set forth for the purposedescribed.

3. The herein-described tool for truing the joints of well-drillingapparatus,the same consisting of similarly-formed yokes or clampsinversely disposed and terminating in heads which are transverselyapertured, a handle fitted to the yokes, a cutting-tool, means for adjustably securing the cuttin g-tool to a yoke, an arch having sleeves atits ends which are fitted. between the heads of the yokes and which haveopenings alining with the openings ot the said heads, aset-screw appliedcentrally of the arch, bolts passing through the openings of the headsand sleeves and con Witnesses:
